Unfortunately there are some regressions in the GPU code that cause
Chromium and Google Chrome to crash, e.g.:
machine # [0709/084047.890436:ERROR:process_memory_range.cc(75)] read out of range[ 30.153484] show_signal: 20 callbacks suppressed

Hopefully this'll be fixed upstream before the final release (there are
bug reports for it) but for the meantime we have to launch the beta and
dev versions with "--use-gl=angle --use-angle=swiftshader".

This most notably fixes cross _evaluation_ of chromium which previously
would fail because makeWrapper relies on runtimeShell which is not
available in the HostTarget package set.
I tested that the native chromium build still works, but haven't tried
cross compiling it yet. There very well may be additional errors, but at
least they will be build errors, not hard to understand evaluation
errors.

Updated firecracker to v0.24.4. This required updating the buildPhase to
point to new compilation result paths.
Formatting changes were performed by `nix-update --format`

Their last Chromium commit is a52d7674cc7 from 2019.
Thank you for maintaining Chromium in the past.

This executable is required to fix a startup error.
TODO: Refactor the Nix expressions to allow chromiumVersionAtLeast, etc.
"everywhere" and investigate the VM test failure.

Would need to temporarily remove "ffmpeg" from gnSystemLibraries and
disable use_thin_lto to fix the build (theoretically).
(cherry picked from commit 5cae43456679428a675fb7074b48ceb5aa3f73e4)
The final linking still fails though, even with llvm-git.
We might have to diable use_thin_lto for now:
ld.lld: error: undefined symbol: snappy::Compress(char const*, unsigned long, std::__1::basic_string<char, std::__1::char_traits<char>, std::__1::allocator<char> >*)

(cherry picked from commit 8af443906d795aa562839f4968566dd58b76c0fd)
If our Chrome derivation is Vulkan enabled, the Chrome GPU process
reliably crashes for me under M92 using the proprietary Nvidia drivers.
This is because the PCI-based GPU detection path fails, and we attempt
to use the Vulkan fallback instead, which then crashes(!!)
Including libpci allows us to use Angle's
src/gpu_info_util/SystemInfo_libpci.cpp path instead, which doesn't
crash, unlike src/gpu_info_util/SystemInfo_vulkan.cpp.

It's worth to think about setting -DDESKTOP_APP_USE_PACKAGED_FONTS=OFF
since it's impossible to install fonts as dependencies of packages with
Nix and tdesktop's widgets are developed only with Open Sans in mind (it
has a lot of hardcoded values and wide fonts like DejaVu may
even go out of widgets' bounds)
